A department store is having a sale.All jeans are on sale for 15% off.if a pair of jeans originally cost $115.00,what is the sale price of jeans? A.$17.25
B.$97.75
C.$100.00
D.$114.85

The answer is 97.75

Step-by-step explanation:

115x.15=17.25

115-17.25=97.75

Multiply both sides of the equation by 6

x/2*6-4*6=x/3*6

3x-24=2x

This effectively got rid of all the fractions.

Now combine liked terms.

3x-2x-24+24=2x-2x+24     I subtracted 2x from both sides and added 24 on both sides.

x=24

We can check our answers

24/2-4=8

and 24/3=8 so my answer is correct

x=24
